hey guys, i just put a new motor in my 93 gs and when i went to start it up the bike just jumps up really high and stays there? i have checked the cables multiple times and all is were it should be. i have tried 2 sets of carbs and they both do the same thing? does anyone have any ideas? thanks.

hmm from my limited knowledge i would say: Idle screw, check to see if the choke is going back in all the way, oh and wait for more advice 

mine did that because the carbs were out of sync..... then it did it cuz there was a vacuum leak in the boots...... then it did it cuz there was a vacuum leak in the caps..... then it did it cuz the choke was adjusted too tight so it was on even though it looked off....  I forget in what order, but it's fairly normal now.  Tried carbs with diff jets? 

that is what mine did when idle screw was not set properly.

i believe there are instructions in the wiki
